Abstract

La présente invention concerne un dispositif pour examiner un objet en mouvement qui comprend un capteur d'images émettant un signal vidéo a, un stroboscope commandé par un signal c, un détecteur de position produisant un signal b quand l'objet arrive à une position prédéterminée, et un appareil d'examen 4 de l'objet, ce dernier comprenant des moyens 42, 44, 46 grâce auxquels une période de temps, précedant et faisant suite au signal de synchronisation horizontale f du capteur d'images, est établie en tant que période d'inactivité durant laquelle il n'est procédé à aucun examen de l'objet. Par ailleurs, le stroboscope est commandé de manière à émettre de la lumière en synchronisme avec le signal de détection de position b quand celui-ci arrive en même temps que le signal de synchronisation verticale e du capteur d'images, ou bien au commencement de la période d'inactivité, immédiatement après le signal b quand ce dernier arrive à un moment autre. L'invention sert essentiellement à examiner des objets en mouvement.The present invention relates to a device for examining a moving object which comprises an image sensor emitting a video signal a, a strobe controlled by a signal c, a position detector producing a signal b when the object arrives at a predetermined position , and an apparatus for examining the object 4, the latter comprising means 42, 44, 46 by which a period of time, preceding and following the horizontal synchronization signal f of the image sensor, is established as period of inactivity during which no examination of the object is carried out. On the other hand, the strobe is controlled so as to emit light in synchronism with the position detection signal b when the latter arrives at the same time as the vertical synchronization signal e from the image sensor, or at the beginning of the period of inactivity, immediately after the signal b when the latter arrives at another time. The main purpose of the invention is to examine moving objects.
